Security update for systemd

This update for systemd provides the following fixes:

Security issues fixed:

- CVE-2018-16864, CVE-2018-16865: Fixed two memory corruptions through attacker-controlled alloca()s (bsc#1120323)
- CVE-2018-16866: Fixed an information leak in journald (bsc#1120323)
- Fixed an issue during system startup in relation to encrypted swap disks (bsc#1119971)

Non-security issues fixed:

- core: Queue loading transient units after setting their properties. (bsc#1115518)
- logind: Stop managing VT switches if no sessions are registered on that VT. (bsc#1101591)
- terminal-util: introduce vt_release() and vt_restore() helpers.
- terminal: Unify code for resetting kbd utf8 mode a bit.
- terminal Reset should honour default_utf8 kernel setting.
- logind: Make session_restore_vt() static.
- udev: Downgrade message when settting inotify watch up fails. (bsc#1005023)
- log: Never log into foreign fd #2 in PID 1 or its pre-execve() children. (bsc#1114981)
- udev: Ignore the exit code of systemd-detect-virt for memory hot-add. In SLE-12-SP3,
80-hotplug-cpu-mem.rules has a memory hot-add rule that uses systemd-detect-virt to
detect non-zvm environment. The systemd-detect-virt returns exit failure code when it
detected _none_ state. The exit failure code causes that the hot-add memory block can
not be set to online. (bsc#1076696)
